With an outside diameter of 0.375 inches, a wire diameter of 0.0475 inches, and a spring rate of 4.86 lb\/in, this spring delivers controlled resistance through its full extension cycle. It has an overall free length of 2.5 inches and extends to a maximum of 4.07 inches under a maximum working load of 10.03 lb. Sold in a package of 3 pieces, it suits applications where consistent restoring force and compact form factor are both required. Mechanical maintenance technicians, OEM assemblers, and industrial service professionals are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis extension spring is suited for light-duty mechanical assemblies where a compact, precise tensile element is needed. Typical applications include HVAC damper linkages, control panel mechanisms, door latches, and general industrial equipment where repeated extension and return cycles occur. Its small diameter and moderate load capacity make it a practical fit for space-constrained assemblies in both residential and light commercial settings. The package quantity of 3 supports service inventory or multi-point installations on the same piece of equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.375 inch outside diameter suits compact mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003e4.86 lb\/in spring rate provides predictable, linear restoring force\u003c\/li\u003e\n  \u003cli\u003eMaximum extended length of 4.07 inches from a 2.5 inch free length\u003c\/li\u003e\n  \u003cli\u003e10.03 lb maximum working load rated by the manufacturer\u003c\/li\u003e\n  \u003cli\u003e0.0475 inch wire diameter for fine-pitch, low-profile spring construction\u003c\/li\u003e\n  \u003cli\u003eSold in a quantity of 3 pieces per package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service stock extension spring for light mechanical assemblies requiring a 0.375 inch OD tensile spring with a 4.86 lb\/in spring rate.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eExtension springs store energy under tension and should always be installed and removed with appropriate hand tools and eye protection, as sudden release can cause injury. Verify that the mounting hooks or loop ends are fully engaged on both anchor points before loading the spring. Do not exceed the rated maximum working load of 10.03 lb, as overextension can permanently deform the spring or cause failure. A licensed mechanic or qualified technician should assess the surrounding assembly for wear before installing replacement springs.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.0475 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 4.07 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 4.86 lb\/in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Load\u003c\/strong\u003e: 10.03 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 3 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GARDNER SPRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: E40C-SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52076030034226,"sku":"E40C-SS","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f5d5bbd0cb4c172042ac3af3109a1e2_d189da56-a38f-4dd8-b5c4-8819e8afc557.jpg?v=1790052332","url":"https:\/\/voomisupply.com\/products\/gardner-spring-e40c-ss-extension-spring-0-375-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
